ABSTRACT:
A coupling hook 5 for a lower steering arm 3 of a three-point attaching device of a tractor has a hook member 6 with a locking catch 7 which is spring-loaded in the direction of the locking position. The locking catch 7 is arranged in a recess 12 of the hook member 6 and extends through an aperture 13 into the bearing recess 10 to receive a bearing ball 11. For the purpose of supporting and guiding the locking catch 7, the hook member 6 is provided with a first stop face 14 and a second supporting stop 15, arranged at a distance therefrom and offset towards the rear. In the locking position, the locking catch 7 is supported on the hook member 6 by means of a first supporting face 19, a second supporting face 21 and a blocking face 22. The assembly is designed in such a way that the second supporting face 21 and the blocking face 22 form part of a recess in the locking catch 7 and that contact between the blocking face 22 and the supporting stop 15 takes place beneath an imaginary connecting line 27 between the contact point between the locking face 25 of the locking catch 7 and the outer face 26 of the bearing ball 11, on the one hand, and the center 29 of the convex supporting stop 15, on the other hand. In this way, an improved locking effect is ensured.
